TEMPORARY OR LOOSE-LEAF BINDER.

Patented Dec. 12, 1905.

Application filed November 10, 1904=. Serial No. 232,069.

To all whom it may concern:

Be it known that I, JOHN W. HUSING, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Temporary or Loose-Leaf thumb-nut.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wher'ein Figure 1 is a perspective view of a temporary binder with the improved. locking mechanism applied thereto, the cover for the movable clamp-plates and one of said plates being partly broken away'for the purpose of illustrating the arrangement of the locking means. Fig. 2 is a detail view, in rear elevation, of the clamp-plates, the file-posts, and the lock mechanism for the movable clamp-plates, said movable clamp-plates and the lock slide-plates being partly sectioned. Fig. 3 is a top plan view of the mechanism disclosed by Fig. 2 of the drawings, the upper movable clamp-plates being partly broken away and the thumb-nut for actuating the locking means being removed; and Fig. 4 is a detail vertical sectional view of the movable clamp-plates, the lock slide-plates arranged therebetween, and the thumb-nut for operating the lock mechanism, said view disclosing the cone for controlling the longitudinal movement of the lock slide-plates.

plates 6 6 are secured. These plates are formed with the perforations 7 7, through which extend the file-posts 5 5, Figs. 1 and 2 of the drawings.

Between the clamp-plates 6 6', which are vertically movable on the file-posts 5 5, the longitudinally-movable lock slide-plates 8 8' are located, which slide-plates are held in position between the said clamp-plates by means of the pins 9. These pins are riveted to the clamp-plates and extend through elongated openings 9 in the lock slide-plates 8 8, Fig. 3 of the drawings.

In the outer end portion of each lock slideplate there is formed an elongated opening 10, through which the file-posts 5 5 extend.

The inner end 11 of each lock slide-plate is beveled, said ends being held spaced or separated by the screw-threaded vertical post 12. This post is riveted to the clamp-plate 6 and extends through a thimble 12 and beyond the top cover of the binder. The thimble 12 is held within an opening in the clamp-plate 6, Figs. 2 and 4 of the drawings, and within said thimble works the shank 13 of the thumbnut 13, which thumb-nut screws onto the threaded post 12.

Upon the threaded post 12 is loosely fitted the cone-nut 14:, which bears against or upon the inclined or beveled edge 11 of the lock slide-plates and as forced downward serves to separate or move apart the slide lock-plates in order to cause the same to bind against the file-posts 5 5 for the purpose of holding the movable clamp-plates 6 6 in adjusted position.

In order to reduce friction to a minimum, there is interspersed between the lower end or shank 13 of the thumb-nut 13 and the upper surface of the cone 14 the Washers 14.

When it is desired to release the clampplates 6 6 in order that the same may be moved away from the lower clamp-plate 4 for the purpose of inserting an additional leaf 3 or to permit the removal of a leaf, the

thumb-nut 13 is turned to move upward on its threaded post 12, when the exertion of a slight upward strain onto the clamp-plates 6 6 will cause the slide-lock plates to move inward or toward each other, thus relieving the bind thereof upon the file-posts 5 5 and releasing the clamp-plates 6 6. When thus re leased, the cover 2 is free to be moved toward or from the bottom cover 1. To lock the parts in any adjusted position for the holding of the leaves 3 firmly between the clampplates of the binder, it is only required that the thumbnut 13 be screwed downward, which causes the shank 13 thereof to bear upon the Washers 14: and force the cone 14: onto and between the beveled surface of the slide lock-plates. As the cone 14: is thus forced downward it spreads apart or separates the slide lock-plates, causing the outer end portion thereof to bind firmly against the file-post, and thus firmly hold the verticallymovable clamp-plates 6 6 against movement.

The cover is prevented against entire separation from the binder by means of the enlarged heads 15 for the file-posts, which heads are screwed onto the said posts after the movable clamp-plates 6 6 have been fitted thereon.

Only a limited upward movement is permitted the thumb-nut 13, for it is prevented from being unscrewed entirely from the post 12 by means of the enlarged head 15 screwed thereon.

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is

1. In a temporary binder, the combination with a cover, of the spaced clamp-plates secured therein, the file-posts on which said plates are vertically movable, the longitudinally-movable lock-plates held between the spaced clamp-plates, a fixed screw-threaded post separating the lock-plates, a cone slidably mounted on the screw-threaded post in contact with said lock-plates and a thumb-nut working on the said post, the movement of which thumb-nut serves to control the position of the cone to actuate the slide lock-plates for engaging the file-posts and locking the clamp-plates against movement, or to permit of the lock-plates moving inward to release the said clamp-plates.

2. In a temporary binder, the combination with a cover, of clamp-plates secured therein,

posts on which the clamp-plates are vertically adjustable, lock slide-plates arranged between the clamp-plates, and means for controlling the movement of the lock slide-plates toward and fromthe binding-posts for locking the clamp-plates thereto or for releasing the same, said means including a screw-threaded post projecting upwardly from the lower plate, a conical wedging member freely movable on said post, an operating-nut having screwthreaded engagement with said post and arranged to impart movement to said conical member, and means on the post for limiting the upward movement of the nut.

3. In a temporary binder, oppositely-disposed clamping-plates mounted for vertical adjustment on vertically-arranged clampingposts, the'said posts, a locking-plate comprising sections arranged intermediate said clamping-plates and adapted to engage and disengage said clamping-posts, and means for'imparting sliding movement to said sections of the clamping-plate including an intermediately-arranged threaded post secured to the lower clamping-plate and projecting upwardly therefrom, a conical wedging member freely movable on said threaded posts, anut having screw-threaded engagement with said threaded posts and adapted to impartmovement to said conical wedging member, and washers interposed between the nut and said conical wedging member.

In witnesswhereof I have hereunto set my JOHN W. HUSING.
